Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and in particular to a pond disinfection device for aquaculture. Background Technology

[0002] In aquaculture, pond disinfection is a crucial step in ensuring the healthy growth of farmed organisms and improving aquaculture efficiency. As an important piece of equipment for pond disinfection, the performance of aquaculture pond disinfection devices directly affects the disinfection effect and the quality of the aquaculture environment. The aquaculture pond disinfection device involved in this utility model mainly uses a motor to drive the stirring shaft to rotate, which in turn drives the stirring blades to agitate the water, achieving uniform diffusion of the disinfectant. Simultaneously, a linkage structure drives the vertical plate to move up and down, promoting vertical water circulation and material exchange.

[0003] In existing technologies, when using such pond disinfection devices, the stirring device is usually installed above the pond, and the motor is started to rotate the stirring shaft and stirring blades. The mechanical stirring action of the stirring blades promotes the diffusion of disinfectant in the water.

[0004] However, the layout and number of stirring blades in traditional disinfection devices are often not reasonable enough. The stirring blades of most devices are distributed in a relatively simple way, which makes it difficult to meet the water mixing needs of different areas of the pond. This results in uneven mixing of water in the middle and corners of the pond, and the disinfectant cannot be fully diffused to all corners. Some areas are not thoroughly disinfected, which increases the risk of disease in aquatic animals. Therefore, a pond disinfection device for aquaculture is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pond disinfection device for aquaculture, which aims to solve the problem of uneven water mixing in the middle and corners of the pond in the prior art, and the inability of the disinfectant to fully diffuse to all corners.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pond disinfection device for aquaculture, comprising a pond, a support rod fixedly connected to the top outer wall of the pond, a top plate fixedly connected to the top end of the support rod, a motor fixedly connected to the top outer wall of the top plate, a mixing mechanism provided inside the pond, the mixing mechanism comprising a first stirring shaft, the outer wall of the first stirring shaft being rotatably connected to the inner wall of the top plate, the top end of the first stirring shaft being fixedly connected to the output end of the motor, a first stirring blade fixedly connected to the outer wall of the first stirring shaft, and a second stirring shaft being driven by the first stirring shaft through a pulley assembly, the outer wall of the second stirring shaft being fixedly connected to a second stirring blade.

[0007] As a further description of the above technical solution: the height of the first stirring blade is higher than the height of the second stirring blade.

[0008] As a further description of the above technical solution: the pulley assembly includes two pulleys and a belt. The two pulleys are respectively fixedly sleeved on the outer walls of the first stirring shaft and the second stirring shaft, and the two pulleys are connected by belt drive.

[0009] As a further description of the above technical solution: the outer wall of the second stirring shaft is rotatably connected to the inner wall of the top plate.

[0010] As a further description of the above technical solution: a hinge block is fixedly connected to the top end of the second stirring shaft, a first connecting rod is hinged to the top of the hinge block, a second connecting rod is hinged to the outer wall of the first connecting rod, a third connecting rod is hinged to the outer wall of the second connecting rod, and a vertical plate is slidably connected to the outer wall of the third connecting rod.

[0011] As a further description of the above technical solution: a trapezoidal plate is fixedly connected to the top outer wall of the third link, and the top outer wall of the trapezoidal plate is in contact with the top inner wall of the vertical plate.

[0012] As a further description of the above technical solution: a compression spring is fixedly connected to the outer wall of the third link, and a fixing plate is fixedly connected to the end of the compression spring away from the third link, and the bottom of the fixing plate is fixedly connected to the outer wall of the top of the top plate.

[0013] As a further description of the above technical solution: a load-bearing ring is fixedly connected to the outer wall of the vertical plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the motor drives the first stirring shaft to rotate, which in turn drives the first stirring blade to stir the surface water in the middle of the pond, promoting horizontal flow and mixing; and the second stirring shaft is rotated through the pulley assembly, and the second stirring blade guides the water flow to the edge corner of the pond, reducing dead zones and allowing the disinfectant to spread more evenly throughout the pond, greatly improving the disinfection effect.

[0016] 2. In this utility model, when the second stirring shaft rotates, its top hinge block drives the first connecting rod to move, which in turn pulls the second and third connecting rods to make linear reciprocating motion. The trapezoidal plate on the third connecting rod uses the inclined surface to push the vertical plate to move up and down. The up and down movement of the vertical plate breaks the static state of the water in the vertical direction, so that the surface water rich in oxygen and disinfectant is brought to the bottom of the pond, providing sufficient oxygen and a good disinfection environment for the bottom-cultured organisms.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 2This utility model provides an embodiment of a pond disinfection device for aquaculture, comprising a pond 1, a support rod 2 fixedly connected to the top outer wall of the pond 1, a top plate 3 fixedly connected to the top of the support rod 2, the support rod 2 being used to install and fix the top plate 3, a motor 4 fixedly connected to the top outer wall of the top plate 3, and a mixing mechanism provided inside the pond 1, the mixing mechanism including a first stirring shaft 5, the outer wall of the first stirring shaft 5 being rotatably connected to the inner wall of the top plate 3, providing a limiting and fixing effect for the first stirring shaft 5, the top of the first stirring shaft 5 being fixedly connected to the output end of the motor 4, the operation of the motor 4 being able to drive the first stirring shaft 5 to rotate. A first stirring blade 8 is fixedly connected to the outer wall of a stirring shaft 5. The rotation of the first stirring shaft 5 can drive the first stirring blade 8 to rotate. There are five first stirring blades 8. The first stirring shaft 5 is connected to a second stirring shaft 6 through a pulley assembly 7. The pulley assembly 7 plays a transmission role. A second stirring blade 9 is fixedly connected to the outer wall of the second stirring shaft 6. There are three second stirring blades 9 on one second stirring shaft 6. The more stirring blades in the middle can effectively stir the water in the middle of the pond 1, while the stirring blades on both sides can guide the water flow to the edge corners of the pond 1, reduce dead water corners, and allow the disinfectant to be more evenly diffused throughout the entire pond 1, thereby improving the disinfection effect.

[0025] Reference Figure 1 - Figure 3 The height of the first stirring blade 8 is higher than that of the second stirring blade 9. The second stirring blade 9 is located in the deep water area, while the first stirring blade 8 is located in the shallow water area. This facilitates the exchange of nutrients at the bottom of the pool with the oxygen-rich surface water, allowing beneficial microorganisms and nutrients to be evenly distributed in the water, providing a more balanced living environment for the cultured organisms and promoting their growth. The pulley assembly 7 includes two pulleys and a belt. The two pulleys are respectively fixedly sleeved on the outer walls of the first stirring shaft 5 and the second stirring shaft 6. The two pulleys are connected by belt drive. The outer wall of the second stirring shaft 6 is rotatably connected to the inner wall of the top plate 3, providing a limiting and fixing effect for the second stirring shaft 6.

[0026] Reference Figure 3 - Figure 4A hinge block 10 is fixedly connected to the top of the second stirring shaft 6. The hinge block 10 rotates in a circular motion following the rotation of the entire second stirring shaft 6. A first connecting rod 11 is hinged to the top of the hinge block 10. The end of the first connecting rod 11 connected to the hinge block 10 also rotates in a circular motion. A second connecting rod 12 is hinged to the outer wall of the first connecting rod 11. The movement of the first connecting rod 11 pulls down the second connecting rod 12. A third connecting rod 13 is hinged to the outer wall of the second connecting rod 12. The second connecting rod 12 pulls the third connecting rod 13 in a linear reciprocating motion. A vertical plate 16 is slidably connected to the outer wall of the third connecting rod 13. The vertical plate 16 can move up and down, breaking the static state of the water in the vertical direction and promoting the exchange between the surface water and the bottom water. The surface water, rich in oxygen and disinfectant, can be carried to the bottom of the pond 1, providing sufficient oxygen and a good disinfection environment for the cultured organisms at the bottom. At the same time, the nutrient-rich water at the bottom can also rise to the surface. The third link 13 is fixedly connected to the top outer wall of the third link 13. The trapezoidal plate 17 can control the vertical plate 16 to move up and down by using the inclined plane under the reciprocating motion of the third link 13. The top outer wall of the trapezoidal plate 17 is in contact with the top inner wall of the vertical plate 16. The compression spring 14 is fixedly connected to the outer wall of the third link 13. The compression spring 14 has the effect of limiting the third link 13 and assisting in the reset. The end of the compression spring 14 away from the third link 13 is fixedly connected to the fixing plate 15. The fixing plate 15 has the effect of fixing and limiting the compression spring 14. The bottom of the fixing plate 15 is fixedly connected to the top outer wall of the top plate 3. The load-bearing ring 18 is fixedly connected to the outer wall of the top plate 3 when not in use. The load-bearing ring 18 can be supported by contacting the top outer wall of the top plate 3 to prevent the weight from falling entirely on the trapezoidal plate 17.

[0027] Working principle: The motor 4 starts, driving the first stirring shaft 5 to rotate. The first stirring blades 8 fixed to the outer wall of the first stirring shaft 5 rotate accordingly. Since there are five first stirring blades 8 located in the shallow water area, they effectively stir the surface water in the middle of the pond 1, promoting horizontal flow and mixing. The first stirring shaft 5 transmits power to the second stirring shaft 6 via the pulley assembly 7. When the second stirring shaft 6 rotates, the three second stirring blades 9 fixed to its outer wall rotate in the deep water area, guiding the water flow to the edges and corners of the pond 1. This, combined with the first stirring blades 8, reduces dead zones, allowing the disinfectant to spread more evenly throughout the pond, enhancing the disinfection effect. As the second stirring shaft 6 rotates, the hinge block 10 fixed at its top moves in a circular motion. The hinge block 10 drives the first connecting rod 11, which in turn pulls the second connecting rod 12. The second connecting rod 12 then pulls the... The three-link rod 13 reciprocates in a straight line. During the reciprocating motion of the third link 13, the trapezoidal plate 17 uses its inclined surface to push the vertical plate 16 up and down. At the same time, the compression spring 14 on the outer wall of the third link 13 plays a role in limiting and assisting in the reset of the third link 13, ensuring the stability and regularity of its movement. When the vertical plate 16 moves up and down, it breaks the static state of the water in the vertical direction. It can not only bring the oxygen-rich and disinfectant-rich water on the surface to the bottom of the pond 1, providing sufficient oxygen and a good disinfection environment for the cultured organisms at the bottom, but also allow the nutrient-rich water at the bottom to rise to the surface, participate in the material cycle, improve the vitality of the entire pond 1 water body, and further optimize the culture environment. When the device stops working, the load-bearing ring 18 on the outer wall of the vertical plate 16 can be controlled and adjusted to be on the top outer wall of the top plate 3, which can support the vertical plate 16 and prevent the weight of the vertical plate 16 from being entirely applied to the trapezoidal plate 17, thus protecting the relevant components.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
